After finding out that God has been manipulating them, Dean and Sam are facing an “existential crisis” in the 15th and final season. “They’re realizing, ‘Well, we’re the Winchesters, but were we really doing this Chuck’s way?'” co-showrunner Andrew Dabb previews. “Part of reclaiming that agency is a big part of the season for them.” Plus, the brothers are “going to start to lose people who, in past seasons, we would’ve never lost — and lose them in a very real way. Our guys are going to realize there’s a certain finality, and some of the things they’ve relied on to get through the day — people, talents, things like that — they are no longer going to be able to roll out. And that’s going to throw them for a loop.” The show’s swan song will also welcome back some departed faces, including the Winchesters’ half-brother Adam(Jake Abel), God’s sister Amara (Emily Swallow) and deceased hunter Eileen (Shoshannah Stern).

BONUS SPOILER!: Jack is still in The Empty when Season 15 starts, and “he’s not coming back in the near future,” Dabb reveals. As for the deal Cas made to save Lucifer’s offspring, “when The Empty becomes more active, a lot of things are going to come to a head.”
